The key points of field management of the latest Chu orange

Chu Orange is a kind of orange variety created by the famous entrepreneur Chu Shijian, so it is named Chu Orange. It was originally a specialty of Yunnan, but with Chu Orange becoming more and more famous, it is now grown in other tropical provinces in China. Chu orange has gradually spread to the whole country, and many people want to introduce and cultivate it. But do you know how to manage Chu Orange after cultivation? The following editor brings you the key points of Chu Orange's field management. let's have a look.

1. Fertilizer and water management

The nutrition requirements of Chu orange are different in each growth stage. In the young tree stage, the focus of fertilization is mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer, and follow the principle of applying a small amount of fertilizer. Then topdressing is applied once after each shoot germination and pruning, usually about 5 times a year. Then it is necessary to properly spray foliar fertilizer in important periods such as flowering and fruit stage and expansion period. We should water the soil in time in spring to keep the soil moist and meet the water demand of Chu orange. However, we should not have too much water, and we should also pay attention to drainage in summer and other high-temperature and high-humidity environments to prevent diseases and insect pests from causing and affecting the growth of Chu orange.

2. Shaping and pruning

The shaping and pruning of Chu orange is the same as fertilizer and water management, and there are different pruning methods for different tree ages. In the young tree stage, about 3 main branches should be cultivated, and two or so lateral branches should be retained on each main branch. the pruning method is mainly to put shoots and pick the heart, so as to cultivate good backbone fruiting branches. Then the adult trees are pruned by thinning and shrinking to improve the permeability of fruit trees and maintain a good tree shape. Generally pruning is carried out before the flower and bud stage, and the pruning method is controlled according to the tree potential and the amount of flowers and fruits. After harvest, undesirable branches such as overlong and dense branches and diseases and insect pests should be removed in time. Then properly cut the strong fruiting branches to promote the fruit of the following year and increase the yield.

3. Flower and fruit management

When we are planting, in order to avoid damage to the roots of Orange trees, we should do a good job of fertilization during the green period and properly spray foliar fertilizers such as trace elements. Do a good job of drainage to prevent the harm of diseases and insect pests. Fruit trees should not leave too much fruit, and bad fruits such as small fruits, diseases and insect pests should be removed in time. Prevent excessive consumption of nutrients and promote the growth of normal fruits. Then it is necessary to properly spray growth regulators and other chemicals to protect flowers and fruits to reduce the phenomenon of physiological fruit drop. Control the growth of summer shoots, wipe buds properly, improve fruit setting rate, and stop the application of nitrogen fertilizer during physiological fruit drop.

4. Harvest and storage

When we harvest, we should control the harvest time according to different directions and uses to ensure the commercial value of the fruit. For example, if it needs to be stored and transported after harvest, it should be harvested when the fruit is about 80% ripe. The mechanical damage of the fruit should be prevented during harvest, which will lead to the wound of the fruit and reduce the storability. If you want to store the fruit after harvest, soak the fruit in a solution such as carbendazim for about half a minute. Put it into a plastic bag after drying, turn it every half a month or so, and find that the rotten fruit should be picked out in time.

The above is a brief introduction to the main points of Chu orange field management. Chu orange field management has a great relationship with its growth and yield. Therefore, if we introduce and cultivate, we must learn good management techniques, so as to ensure their own planting benefits. That's all for today's introduction.
